ABSTRACT

The present invention relates to new compounds of formula (I), wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , and R 8  independently from each other are hydrogen; C 1 -C 18 alkyl; C 2 -C 18 alkenyl; C 5 -C 7 , cycloalkyl; C 1 -C 6 alkylene-C 5 -C 7 , cycloalkyl; R 9  is hydrogen; C 1 -C 18 alkyl; C 2 -C 18 alkenyl; C 5 -C 7 cycloalkyl; C 1 -C 6 alkylene-C 5 -C 7 cycloalkyl; C 6 -C 10 aryl; A is —S—; —O— or —NR 10 —, wherein R 10  has the same meanings as R 9 ; X is COOR 11 ; CONR 12 R 13 ; SO 3 , R 14 ; or SO 2 NR 15 R 16 , wherein R 11 , R 12 , R 13 , R 14 , R 15 , and R 16 , have independently from each other the same meanings as R 9 ; to their preparation and to their use as UV absorbers in cosmetic and pharmaceutical formulations.

The present invention relates to anisyl-bis(arylamino)-triazines, to the preparation of these compounds and to their use as UV absorbers in cosmetic and pharmaceutical formulations.

Depending on their wavelength, UV rays are divided in UV-A rays (320-400 nm) and UV-B rays (280-320 nm). The harmful effect, in particular the occurrence of sunburn (erythema), increases not only with the duration of exposure but also with decreasing wavelength and is thus significantly more strongly marked in the case of UV-B radiation than in the case of UV-A radiation. Since erythemas can occur even after short exposure to the sun, in some cases after 20-30 minutes, efficient protection against this radiation is of particular importance.

Ultra violet light absorbing compounds (UV-absorbers) do not absorb the complete spectrum of ultra violet light to the same extent at each wavelength. Characteristics of UV-absorbers are therefore the wavelength at which absorption is largest (in nm), and the absorption percentage at this wavelength (relative, calculated using the law of Lambert-Beer). Both this wavelength and absorption percentage at maximum absorbency can be influenced by other components present together with the UV-absorber.

It was now found that specific anisyl-bis(arylamino)-triazines are very effective UV absorbers.

Therefore, the present invention relates to compounds of formula

A further embodiment of the present invention is a process for the preparation of compounds of formula (1), characterized in that one mol of at least one compound of formula

R₁, R₂, R₃, R₄ and R₉ have independently from each other the same meanings as defined in formula (1) and formula (2)

and Y is halogen, preferably Cl,

is reacted with at least two mols of at least one compound of formula

R₅, R₆, R₇, R₈, A and X have independently from each other the same meanings as defined in formula (1) and formula (2).

The reaction is preferably carried out in an inert solvent, for example dioxan.

The reaction temperature is preferably from 50 to 100° C., more preferably from 60 to 90° C.

The obtained reaction product is purified by conventional methods, such as for example recrystallisation.

The compounds of the formula (1) according to the present invention are particularly suitable as UV filters, i.e. for protecting ultraviolet-sensitive organic materials, in particular the skin and hair of humans and animals, from the harmful effects of UV radiation. These compounds are therefore suitable as sunscreens in cosmetic, pharmaceutical and veterinary medical preparations. These compounds can be used both in dissolved form and in the micronized state.

The UV absorbers according to the present invention can be used either in the dissolved state (soluble organic filters, solubelized organic filters) or in the micronised state (nanoscalar organic filters, particulate organic filters, UV-absorber pigments).

Any known process suitable for the preparation of microparticles can be used for the preparation of the micronised UV absorbers, for example:

-   -   wet-milling (low viscous micronisation process for pump-able         dispersions), with a hard grinding medium, for example zirconium         silicate balls in a ball mill and a protective surfactant or a         protective polymer in water or in a suitable organic solvent;     -   wet-kneading (high viscous micronisation process non pump-able         pastes) using a continuous or discontinuous (batch) kneader. For         a wet-kneading process a solvent (water or cosmetically         acceptable oils), a grinding-aid (surfactant, emulsifier) and a         polymeric grinding aid may be used.     -   Both processes may be used respectively     -   spray-drying from a suitable solvent, for example aqueous         suspensions or suspensions containing organic solvents, or true         solutions in water, ethanol, dichloroethane, toluene or         N-methylpyrrolidone etc.     -   by the expansion according to the RESS process (Rapid Expansion         of Supercritical Solutions) of supercritical fluids (e.g. CO₂)         in which the UV filter or filters is/are dissolved, or the         expansion of fluid carbon dioxide together with a solution of         one or more UV filters in a suitable organic solvent;     -   by reprecipitation from suitable solvents, including         supercritical fluids (GASR process=Gas Anti-Solvent         Recrystallisation/PCA process=Precipitation with Compressed         Anti-solvents).

As milling apparatus for the preparation of the micronised organic UV absorbers there may be used, for example, a jet mill, ball mill, vibratory mill or hammer mill, preferably a high-speed mixing mill. Even more preferably mills are modern ball mills, manufactures of these mill-types are for example Netzsch (LMZ-mill), Drais (DCP-viscoflow or cosmo), Buihler AG (centrifugal mills) or Bachhofer. The grinding is preferably carried out with a grinding aid. As kneading apparatus for the preparation of the micronised organic UV absorbers examples are typical sigma-hook batch kneaders but also serial batch kneaders (IKA-Werke) or continuous kneaders (Contiuna from Werner und Pfleiderer).

Useful low molecular weight grinding aids for all the above micronizing processes are surfactants and emulsifies as disclosed below in the chapters “emulsifiers” and “surfactants”.

Useful polymeric grinding aids for water dispersion are cosmetically acceptable water soluble Polymers with Mw>5000 g/mol for example: Acrylates (Salcare types), modified or non-modified polysaccharides, polyglucosides or xanthan gum. Furthermore an alkylated vinylpyrrolidone polymer, a vinylpyrrolidone/vinyl acetate copolymer, an acyl glutamate, an alkyl polyglucoside, ceteareth-25 or a phospholipid may be used. Oil dispersions may contain cosmetically acceptable waxy polymers or natural waxes as polymeric grinding aid to adjust viscosity during and after processing.

Useful solvents are water, brine, (poly-)ethylenglycol or glycerine for water-soluble dispersions and also cosmetically acceptable oils like described under “emollients” for oil-soluble dispersions.

The micronised UV absorbers so obtained usually have an average particle size from 0.02 to 2 micrometer, preferably from 0.05 to 1.5 micrometer and more especially from 0.1 to 1.0 micrometer.

The UV absorbers can also be used dry in powder form. For that purpose the UV absorbers are subjected to known grinding methods, such as vacuum atomization, countercurrent spray-drying etc. Such powders have a particle size of from 0.1 micrometer to 2 micro-meter.

To avoid the occurrence of agglomeration, the UV absorbers can be coated with a surface-active compound prior to the pulverisation process, for example with an anionic, non-ionic or amphoteric surfactant, e.g. a phospholipid or a known polymer, such as PVP, an acrylate etc.

The cosmetic formulations or pharmaceutical compositions according to the present invention can also contain one or more than one further UV filter as described in table 1-3.

The cosmetic or pharmaceutical preparations can be prepared by physically mixing the UV absorber(s) with the adjuvant using customary methods, for example by simply stirring together the individual components, especially by making use of the dissolution properties of already known cosmetic UV absorbers, for example octyl methoxy cinnamate, salicylic acid isooctyl ester, etc. The UV absorber can be used, for example, without further treatment, or in the micronised state, or in the form of a powder.

Cosmetic or pharmaceutical preparations contain from 0.0540% by weight, based on the total weight of the composition, of one UV absorber or UV absorber mixtures.

Preference is given to the use of mixing ratios of the UV absorber of formula (1) according to the invention and optionally further light-protective agents (as described in table 1-3) from 1:99 to 99:1, especially from 1:95 to 95:1 and preferably from 10:90 to 90:10, based on weight. Of special interest are mixing ratios of from 20:80 to 80:20, especially from 40:60 to 60:40 and preferably approximately 50:50. Such mixtures can be used, inter alia, to improve solubility or increase UV absorption.

The UV absorbers of formula (1) according to the present invention or combinations of UV filters are useful to protect skin, hair and/or natural or artificial hair color.

Further substances that come into consideration as esterase inhibitors are sterol sulfates or phosphates, for example lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, for example glutaric acid, glutaric acid monoethyl ester, glutaric acid diethyl ester, adipic acid, adipic acid monoethyl ester, adipic acid diethyl ester, malonic acid and malonic acid diethyl ester and hydroxycarboxylic acids and esters thereof, for example citric acid, malic acid, tartaric acid or tartaric acid diethyl ester. Antibacterial active ingredients that influence the germ flora and kill or inhibit the growth of sweat-decomposing bacteria can likewise be present in the preparations (especially in stick preparations). Examples include chitosan, phenoxyethanol and chlorhexidine gluconate. 5-chloro-2-(2,4-dichlorophenoxy)-phenol (Triclosan, Irgasan, Ciba Specialty Chemicals Inc.) has also proved especially effective.

Anti-Dandruff Agents

As anti-dandruff agents there may be used, for example, climbazole, octopirox and zinc pyrithione. Customary film formers include, for example, chitosan, microcrystalline chitosan, quaternised chitosan, polyvinylpyrrolidone, vinylpyrrolidone/vinyl acetate copolymers, polymers of quaternary cellulose derivatives containing a high proportion of acrylic acid, collagen, hyaluronic acid and salts thereof and similar compounds.

Antioxidants

In addition to the primary light-protective substances it is also possible to use secondary light-protective substances of the antioxidant kind that interrupt the photochemical reaction chain triggered when UV radiation penetrates the skin or hair. Typical examples of such anti-oxidants are amino acids (e.g. glycine, histidine, tyrosine, tryptophan) and derivatives thereof, imidazoles (e.g. urocanic acid) and derivatives thereof, peptides, such as D,L-carnosine, D-camosine, L-carnosine and derivatives thereof (e.g. anserine), carotinoids, carotenes, lycopene and derivatives thereof, chlorogenic acid and derivatives thereof, lipoic acid and derivatives thereof (e.g. dihydrolipoic acid), aurothioglycose, propylthiouracil and other thiols (e.g. thioredoxin, glutathione, cysteine, cystine, cystamine and the glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl, lauryl, palmitoyl, oleyl, linoleyl, cholesteryl and glyceryl esters thereof) and also salts thereof, dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and derivatives thereof (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts) and also sulfoximine compounds (e.g. buthionine sulfoximines, homocysteine sulfoximine, buthionine sulfones, penta-, hexa-, hepta-thionine sulfoximine), also (metal) chelating agents (e.g. hydroxy fatty acids, palmitic acid phytic acid, lactoferrin), hydroxy acids (e.g. citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, bilirubin, biliverdin, EDTA, EDDS, EGTA and derivatives thereof, unsaturated fatty acids and derivatives thereof (e.g. linolenic acid, linoleic acid, oleic acid), folic acid and derivatives thereof, ubiquinone and ubiquinol and derivatives thereof, vitamin C and derivatives (e.g. ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (e.g. vitamin E acetate), vitamin A and derivatives (e.g. vitamin A palmitate) and also coniferyl benzoate of benzoin resin, rutinic acid and derivatives thereof, glycosylrutin, ferulic acid, furfurylidene glucitol, carnosine, butyl hydroxytoluene, butyl hydroxyanisole, nordihydroguaiaretic acid, trihydroxybutyrophenone, uric acid and derivatives thereof, mannose and derivatives thereof, superoxide dismutase, N-[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]sulfanilic acid (and salts thereof, for example the disodium salts), zinc and derivatives thereof (e.g. ZnO, ZnSO₄), selenium and derivatives thereof (e.g. selenium methionine), stilbene and derivatives thereof (e.g. stilbene oxide, trans-stilbene oxide) and the derivatives suitable according to the invention (salts, esters, ethers, sugars, nucleotides, nucleosides, peptides and lipids) of those mentioned active ingredients. HALS (=“Hindered Amine Light Stabilizers”) compounds may also be mentioned. The amount of antioxidants present is usually from 0.001 to 30% by weight, preferably from 0.01 to 3% by weight, based on the weight of the UV absorber of formula (1).

Hydrotropic Agents

To improve the flow behaviour it is also possible to employ hydrotropic agents, for example ethoxylated or non ethoxylated mono-alcohols, diols or polyols with a low number of carbon atoms or their ethers (e.g. ethanol, isopropanol, 1,2-dipropanediol, propyleneglycol, glyerin, ethylene glycol, ethylene glycol monoethylether, ethylene glycol monobutylether, propylene glycol monomethylether, propylene glycol monoethylether, propylene glycol monobutylether, diethylene glycol monomethylether; diethylene glycol monoethylether, diethylene glycol monobutylether and similar products). The polyols that come into consideration for that purpose have preferably from 2 to 15 carbon atoms and at least two hydroxy groups. The polyols may also contain further functional groups, especially amino groups, and/or may be modified with nitrogen. Typical examples are as follows: glycerol, alkylene glycols, for example ethylene glycol, diethylene glycol, propylene glycol, butylene glycol, hexylene glycol and also polyethylene glycols having an average molecular weight of from 100 to 1000 Dalton; technical oligoglycerol mixtures having an intrinsic degree of condensation of from 1.5 to 10, for example technical diglycerol mixtures having a diglycerol content of from 40 to 50% by weight; methylol compounds, such as, especially, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol and dipentaerythritol; lower alkyl-glucosides, especially those having from 1 to 8 carbon atoms in the alkyl radical, for example methyl and butyl glucoside; sugar alcohols having from 5 to 12 carbon atoms, for example sorbitol or mannitol; sugars having from 5 to 12 carbon atoms, for example glucose or saccharose; amino sugars, for example glucamine; dialcohol amines, such as diethanolamine or 2-amino-1,3-propanediol.

Preservatives and Bacteria-Inhibiting Agents

Suitable preservatives include, for example, Methyl-, Ethyl-, Propyl-, Butyl-parabens, Benzalkonium chloride, 2-Bromo-2-nitro-propane-1,3-diol, Dehydroacetic acid, Diazolidinyl Urea, 2-Dichloro-benzyl alcohol, DMDM hydantoin, Formaldehyde solution, Methyldibromoglutanitrile, Phenoxyethanol, Sodium Hydroxymethylglycinate, Imidazolidinyl Urea, Triclosan and further substance classes listed in the following reference: K. F. DePolo—A short textbook of cosmetology, Chapter 7, Table 7-2,7-3, 7-4 and 7-5, p 210-219.

Bacteria-Inhibiting Agents

Typical examples of bacteria-inhibiting agents are preservatives that have a specific action against gram-positive bacteria, such as 2,4,4′-trichloro-2′-hydroxydiphenyl ether, chlorhexidine (1,6-di(4-chlorophenyl-biguanido)hexane) or TCC (3,4,4′-trichlorocarbanilide). A large number of aromatic substances and ethereal oils also have antimicrobial properties. Typical examples are the active ingredients eugenol, menthol and thymol in clove oil, mint oil and thyme oil. A natural deodorising agent of interest is the terpene alcohol farnesol (3,7,11-trimethyl-2,6,10-dodecatrien-1-ol), which is present in lime blossom oil. Glycerol monolaurate has also proved to be a bacteriostatic agent. The amount of the additional bacteria-inhibiting agents present is usually from 0.1 to 2% by weight, based on the solids content of the preparations.

Perfume Oils

There may be mentioned as perfume oils mixtures of natural and/or synthetic aromatic substances. Natural aromatic substances are, for example, extracts from blossom (lilies, lavender, roses, jasmine, neroli, ylang-ylang), from stems and leaves (geranium, patchouli, petitgrain), from fruit (aniseed, coriander, carraway, juniper), from fruit peel (bergamot, lemons, oranges), from roots (mace, angelica, celery, cardamom, costus, iris, calmus), from wood (pinewood, sandalwood, guaiacum wood, cedarwood, rosewood), from herbs and grasses (tarragon, lemon grass, sage, thyme), from needles and twigs (spruce, pine, Scots pine, mountain pine), from resins and balsams (galbanum, elemi, benzoin, myrrh, olibanum, opoponax). Animal raw materials also come into consideration, for example civet and castoreum. Typical synthetic aromatic substances are, for example, products of the ester, ether, aldehyde, ketone, alcohol or hydrocarbon type. Aromatic substance compounds of the ester type are, for example, benzyl acetate, pheno; tyethyl isobutyrate, p-tert-butylcyclohexyl acetate, linalyl acetate, dimethylbenzylcarbinyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, ethylmethylphenyl glycinate, allylcyclohexyl propionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether; the aldehydes include, for example, the linear alkanals having from 8 to 18 hydrocarbon atoms, citral, citronellal, citronellyl oxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal; the ketones include, for example, the lonones, isomethylionone and methyl cedryl ketone; the alcohols include, for example, anethol, citronellol, eugenol, isoeugenol, geraniol, linalool, phenyl ethyl alcohol and terpinol; and the hydrocarbons include mainly the terpenes and balsams. It is preferable, however, to use mixtures of various aromatic substances that together produce an attractive scent. Ethereal oils of relatively low volatility, which are chiefly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, clove oil, melissa oil, oil of cinnamon leaves, lime blossom oil, juniper berry oil, vetiver oil, olibanum oil, galbanum oil, labolanum oil and lavandin oil. Preference is given to the use of bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenyl ethyl alcohol, hexyl cinnamaldehyde, geraniol, benzyl acetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, tangerine oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, muscatel sage oil, damascone, bourbon geranium oil, cyclohexyl salicylate, vertofix coeur, iso-E-Super, Fixolide NP, evemyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romillat, irotyl and floramat alone or in admixture with one another.

Colourants

There may be used as colourants the substances that are suitable and permitted for cosmetic purposes, as compiled, for example, in the publication “Kosmetische Facrbemittel” of the Farbstoffkommission der Deutschen Forschungsgemeinschaft, Verlag Chemie, Weinheim, 1984, pages 81 to 106. The colourants are usually used in concentrations of from 0.001 to 0.1% by weight, based on the total mixture.

Other Adjuvants

It is furthermore possible for the cosmetic preparations to contain, as adjuvants, anti-foams, such as silicones, structurants, such as maleic acid, solubilisers, such as ethylene glycol, propylene glycol, glycerol or diethylene glycol, opacifiers, such as latex, styrene/PVP or styrene/acrylamide copolymers, complexing agents, such as EDTA, NTA, alaninediacetic acid or phosphonic acids, propellants, such as propane/butane mixtures, N₂O, dimethyl ether, CO₂, N₂ or air, so-called coupler and developer components as oxidation dye precursors, reducing agents, such as thioglycolic acid and derivatives thereof, thiolactic acid, cysteamine, thiomalic acid or mercaptoethanesulfonic acid, or oxidising agents, such as hydrogen peroxide, potassium bromate or sodium bromate.

Suitable insect repellents are, for example, N,N-diethyl-m-toluamide, 1,2-pentanediol or insect repellent 3535; suitable self-tanning agents are, for example, dihydroxyacetone and/or erythrulose or dihydroxy acetone and/or dihydroxy acetone precursors as described in WO 01/85124 and/or erythrulose.

Polymeric Beads or Hollow Spheres as SPF Enhancers

The combination of the UV-absorbers and UV-absorber combinations, listed above, with SPF enhancers, such as non-active ingredients like Styrene/acrylates copolymer, silica beads, spheroidal magnesium silicate, crosslinked Polymethylmethacrylates (PMMA; Micopearl M305 Seppic), can maximize better the UV protection of the sun products. Holosphere additives (Sunspheres® ISP, Silica Shells hobo.) deflect radiation and the effective path length of the photon is therefore increased. (EP0893119). Some beads, as mentioned previously, provide a soft feel during spreading. Moreover, the optical activity of such beads, e.g. Micropearl M305, cans modulate skin shine by eliminating reflection phenomena and indirectly may scatter the UV light. When formulated in O/W emulsions, the preferably amount of such SPF enhancers should represent 1% to 10% of the total amount of the emulsion.

EXAMPLES Example 1 Preparation of the Compound of Formula

A mixture consisting of 6.4 g 4-aminobenzoeacidethylester (0.025 mol), 8.7 g N,N-dimethylacetamid (0.0527) and 20 ml dioxan (0.23 mol) are added drop by drop to a solution of 6.4 g 2,4-dichloro-6-(4-methoxyphenyl)-[1,3,5]-triazine (0.025 mol) in 80 ml dioxan (0.92). The reaction solution is stirred 4.5 h at 80° C. Afterwards 100 ml water (0.18 mol) is added slowly.

The reaction product is filtered off at 20° C. and washed with dioxan and water. The reaction is also recrystallized with dimethylformamide boiled in methanol.

The obtained product is dried in vacuum. The yield of the white product is 4.2 g (32.7%).
